tempest brothers becoming op with there nation

Chapter 0:A whole new wrld

Darkness wrapped around the cavern like a heavy shroud, broken only by the faint shimmer of mineral veins embedded in the walls. The scent of damp stone clung to the air, each droplet of water echoing like a heartbeat in the silence.

Joshua's translucent body quivered, his mind struggling to process what had happened. The warmth in his core pulsed in perfect rhythm, a delicate balance between two opposing forces buried within him.

Light and Darkness.

Angel and Demon.

His system's voice whispered in the back of his mind, calm and mechanical.

[Unique Skill: Dual Harmony — Active.]

[Balancing Celestial and Infernal Energies...]

[Equilibrium Achieved.]

Joshua could feel it — the constant tug-of-war inside him. Two halves fighting for dominance, yet neither one overpowering the other. It was... natural. As if he'd always been this way.

"Alright," Joshua muttered. "I'm a slime now... great."

From nearby, a familiar voice echoed, tinged with dry humor.

"Hey, could be worse. At least you're not some bug."

Joshua's core flickered, the closest thing to a chuckle he could manage.

Then the ground trembled.

A low, rumbling growl filled the cavern, making Joshua's system flare in warning.

[Threat Detected: Catastrophic.]

[Survival Rate: 0.002% without intervention.]

Joshua's core tensed. Whatever was lurking in the shadows could end him in an instant.

"Relax," Rimuru's voice called, oddly calm. "He's not gonna kill us. Right, Veldora?"

A gust of wind swept through the cavern as two golden eyes opened in the darkness. Their sheer presence pressed against Joshua like a storm threatening to break.

The dragon emerged — massive, obsidian scales shimmering under the dim light. Power radiated from him in waves, saturating the air with raw, unyielding force.

"You dare summon me so casually, slime?" Veldora's voice boomed, shaking the walls.

Joshua's mind raced. The pressure alone was enough to crush him. Yet... there was something else beneath it. Loneliness.

His system whispered again.

[Unique Skill Detected: Divine Insight — Origin: Individual Veldora.]

[Analyzing Soul Signature...]

[Compatibility: 67%]

Joshua's core pulsed as knowledge trickled into him — faint whispers of Veldora's essence imprinting themselves onto his system. This dragon... he had been sealed here for centuries.

Alone.

Just like they were.

"I... I think I understand," Joshua muttered.

Veldora's eyes narrowed.

"Do you now, little slime?"

Joshua's translucent body flickered — light and darkness shimmering beneath the surface.

"You hate being alone... don't you?"

The dragon's gaze hardened, but something flickered behind the pride — a crack in the wall he'd built around himself.

Rimuru bounced forward, his voice softer.

"You're not the only one, Veldora... we've both lost everything too."

The cavern fell into silence, broken only by the distant drip of water.

Finally, the dragon let out a deep rumble — not anger, but something quieter.

"Very well... You two amuse me."

A low glow radiated from Veldora's core, casting golden patterns across the cave walls.

"I shall grant you my name — Tempest. A name carries power in this world... consider it a mark of my favor."

Joshua's system flared, the warmth inside him intensifying.

[Name Registration Required.]

[Assign Name: Joshua Tempest?]

Joshua's core pulsed, the two forces within him flaring brighter.

"I... I accept," he whispered.

[Name Registered: Joshua Tempest.]

[Title Acquired: Tempest Brother.]

Rimuru's body shimmered as his name finalized, the echoes of Veldora's power settling into them both.

At that moment, something shifted deep within Joshua — a spark igniting in the depths of his core.

[Unique Skill Evolution Detected.]

[Dual Harmony → Eclipsed Balance]

[Skill Effect: Grants the ability to harmonize both Celestial and Infernal energies, allowing the user to shift between Light and Dark states at will.]

Joshua's mind reeled as the knowledge poured into him — two forms, two powers, both bound by a single will.

Rimuru's voice broke through the silence.

"Heh... the Tempest Brothers, huh? Has a nice ring to it."

Joshua's core flickered — the closest thing to a smile he could manage.

"Yeah... it does."

The cavern seemed smaller now, as if the storm had finally passed.

For the first time since their rebirth, Joshua felt something stir beneath the surface.

Hope.
